it depends how long of a shot you would be taking i think 50 yards or 100 or less a smoothbore would be ok, but i would get a rifled barrle, because the are more accurate at longer distance, that is what i am doing, and i also got a single shot, i have hear they are more accurate, but i am not sure if that is true, but i also like single shots, so really the action is your choice. hope this helps
